I identify myself with both sides. On the one hand, I am very much a Gentile. I would not be allowed into God's family by birth and I am very conscious of the blessed gift I have been given to be adopted. My natural heritage would not be one that leads to eternal life, let alone the joy and peace given to those who belong to God. I must never fall into the deceptive trap of thinking that I am superior to the natural-born, for they of course are either growing from the vine without scars from the graft (if they have never rejected the Messiah) or are more naturally brought back into the family than I, who was born outside and brought in later.
On the other hand, I was born and raised to be Christian. I was never in ignorance of the Truth, never left to my own devices far away from God. I cannot plead the innocence of someone who never encountered the Lord; if I choose to do what is wrong, then I cannot pretend that I thought it was right. Yet even someone who chooses to disobey God in a very significant way, breaking their connection with His family, can be grafted back in. There is no hopeless case.
